Armor - An armor panel adapted to protect a body from an incoming projectile, the armor panel comprising an armor member constituted by at least one layer. The layer is encapsulated within and pressed upon by a wrapping as a result of an arresting process. The panel has a front, rear and side walls. The wrapping is preformed, prior to the process, with at least one outlet hole at least one of the rear and side walls. Through the outlet hole, air trapped within the armor panel prior to the arresting process, and/or excess gasses produced during the process, are allowed to escape.

Ballistic armor - A composite armor plate with a layer of pellets in a binder matrix, the pellets having domed front and planar back end and a reduced weight. A method of producing the plate comprises providing front and back layers, applying binder material to the pellets and the layers, and heating the binder material to form the matrix and bind the front and back layers thereto. Each pellet may be coated with a primer adapted to facilitate the binding.

UNDERBELLY FOR AN ARMORED VEHICLE - An underbelly for an armored vehicle is provided, configured for providing ballistic protection against a detonation of an explosive device detonated substantially therebelow. The underbelly comprises a central portion having a lowermost area, sidewalls extending upwardly therefrom, the central portion and sidewalls constituting a main armor of the underbelly, and an auxiliary armor panel disposed so as to project downwardly from the lowermost area of the central portion. Upper portions of the sidewalls are free of any auxiliary armor panel.

ARMOR MODULE - An armor module for protecting a surface against an explosively formed projectile (EFP) threat is provided. The armor module is configured for mounting on the surface and comprises at least one armor assembly having a hard layer disposed facing the threat and being configured to fragment the EFP, thus forming residuals of the original EFP threat; a unidirectional fiber layer disposed behind the hard layer; and a catcher layer behind the unidirectional fiber layer, the catcher layer being made of a material exhibiting a level of ballistic protection such that a layer of the material being of the same thickness as the unidirectional fiber layer absorbs at least 20% more energy than is the unidirectional fiber layer for the same threat.

Multi-Functional Armor System - A ballistic armor adapted to protect against armor piercing projectiles and to withstand multiple impacts of fragment simulating projectiles of a predetermined type, traveling at an initial velocity not exceeding a first velocity. The armor comprises a main armor layer and an auxiliary layer. The main armor layer is adapted to absorb most of the energy of the armor piercing projectiles and to withstand the impacts of the fragment simulating projectiles traveling at a velocity not exceeding a second velocity which is lower than said first velocity. The auxiliary layer is disposed in front of the main armor layer to face the projectiles, and is made of a material which is adapted to undergo a ductile failure mode when perforated by said fragment simulating projectiles and thereby experience localized deformation in the vicinity of each perforation, and which is adapted to cause the fragment simulating projectiles to experience such an energy loss associated with the perforation and deformation as to reduce their velocity from the initial velocity to a velocity not exceeding the second velocity.

Armor module and an armor array used therein - According to the present invention there is provided an armor array for protecting a body to be protected from an incoming projectile having an anticipated impact direction. The armor array is constituted by at least a first and a second armor cassette, each comprising a top base plate and a bottom base plate sandwiching therebetween an expandable layer. The first and second armor cassettes are spaced apart by an intermediate depressible panel having a top and a bottom face, such that the bottom base plate of the first armor cassette faces the top face of the intermediate depressible panel and the top base plate of the second cassette faces the bottom face of the intermediate depressible panel. The armor array is constructed such that upon expansion of the expandable layer, caused by the impact of the incoming projectile, at least one of the bottom base plate of the first armor cassette and the top base plate of the second armor cassette is urged towards the intermediate depressible panel and depresses it.

SENSING DEVICE WITH REDUCED ENERGY CONSUMPTION - The presently disclosed subject matter includes a sensor device, and a method of operating thereof. The sensor device comprises a processing unit being operatively connected to a sensor unit comprising a sensor characterized by adaptable sampling frequency. The sensor being configured to periodically sample, in a first sampling frequency, a physical quantity and generate a signal indicative of a detected physical quantity. The processing unit is configured to receive the signal and determine a detected frequency of the signal and to adapt the first sampling frequency to the detected frequency. The adapting comprising calculating a difference between the first sampling frequency and the detected frequency and instructing the sensor to increase the first frequency, if the difference is less than a first predefined value; and to decrease the first frequency, if the difference is less than a second predefined value.
